1 / 7DC Fuse Holder
RT18-63X 1P DIN Rail Fuse Holder 63A 690V
When a single-phase circuit carries heavy loads — main feeder taps, sub-distribution boards, large HVAC units, or high-power machine tools — a 32A fuse holder is not enough. The Soltree RT18-63X 1P is rated at 63A and designed for 14x51mm cylindrical fuse links, making it the right choice for high-current single-phase applications that require robust overload and short-circuit protection. Its flame-retardant PVC housing and high-purity copper contacts ensure low contact resistance, minimal heat generation, and stable performance under continuous heavy load at up to 690V AC. The integrated red LED indicator lights up the moment the fuse blows, so maintenance staff can identify and clear the fault quickly without test equipment. A snap-on 35mm DIN rail design and screw terminals — rated for 4mm²–16mm² wire — allow straightforward installation in main distribution boards and industrial control cabinets. Note: fuse links are sold separately.
